The interior uses of Hyaloclastite include Countertops, Decorative aggregates, Homes and Interior decoration whereas the interior uses of Dunite include Decorative aggregates and Interior decoration. Due to some exceptional properties of Hyaloclastite and Dunite, they have various applications in construction industry. The uses of Hyaloclastite in construction industry include Building houses or walls, Construction aggregate and that of Dunite include As dimension stone, Cement manufacture, Construction aggregate, For road aggregate, Making natural cement, Raw material for the manufacture of mortar.
More about Hyaloclastite and Dunite
Here you can know more about Hyaloclastite and Dunite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Hyaloclastite and Dunite consists of mineral content and compound content. The mineral content of Hyaloclastite includes Calcite, Chlorite and mineral content of Dunite includes Amphibole, Chromite, Garnet, Magnesium, Olivine, Phlogopite, Plagioclase, Pyroxene. You can also check out the list of all Igneous Rocks. When we have to compare Hyaloclastite vs Dunite, the texture, color and appearance plays an important role in determining the type of rock. Hyaloclastite is available in brown, grey, yellow colors whereas, Dunite is available in dark greenish - grey colors. Appearance of Hyaloclastite is Dull and that of Dunite is Rough and Shiny. Properties of rock is another aspect for Hyaloclastite vs Dunite. The hardness of Hyaloclastite is 1-2 and that of Dunite is 3.5-4. The types of Hyaloclastite are Welded tuff, Rhyolitic tuff, Basaltic tuff, Trachyte tuff and Andesitic tuff. whereas types of Dunite are Dunite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Hyaloclastite is while that of Dunite is white. The specific heat capacity of Hyaloclastite is 0.84 kJ/Kg K and that of Dunite is 1.25 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Hyaloclastite is heat resistant whereas Dunite is heat resistant, pressure resistant, wear resistant.
